Techniques of fertilization and watering for jujube trees

Jujube has extremely important economic value, and its cultivation area is also gradually increasing. In order to improve the yield and quality of jujube and increase its income, the fertilization and watering method of jujube is very important. The following editor brings jujube watering and fertilization methods in different periods, hoping to help you.

1. Fertilization for jujube trees

1. Early application of base fertilizer

Jujube is a flowering tree species in the same year, the spring germination begins, with the growth of jujube hanging, its leaf axilla will also appear inflorescence, which needs a lot of nutrients in flowering, so it is necessary to apply base fertilizer early to improve the quality of flower bud differentiation. The base fertilizer is mainly rotten farm manure, mixed with an appropriate amount of nitrogen, phosphorus and potassium compound fertilizer, and applied as early as possible after harvest to meet the needs of flowering, flowering and fruiting of jujube trees in spring. if the basic fertilizer is not applied in autumn, it should be applied in time after thawing in the following spring. The fertilization of young trees is mainly applied in annular ditch, supplemented by radiation ditch, and the soil should be covered and watered after fertilization; in the full fruit stage, about 1000 kg of farm manure is applied to each tree, and an appropriate amount of compound fertilizer is added.

2. Skillfully applying topdressing

In order to reduce the physiological fruit drop, 1-1.5 kg N-P-K compound fertilizer was applied to each jujube tree after flowering, and 1-1.5 kg N-P-K compound fertilizer was applied to each jujube tree after flowering and fruit expansion period. At the same time, we should also pay attention to spraying fertilizer on the leaves, generally spraying 0.3% urea solution every other half month in the early stage and 0.3% potassium dihydrogen phosphate solution in the later stage. Fertilizer spraying should be done before 10:00 in the morning or after 4 p.m., when there is dew in the morning, it should be sprayed after the dew dries.

Second, watering

Jujube is relatively tolerant to drought. In order to improve its fruit setting rate, we should pay attention to timely watering and loosen the soil to preserve soil moisture. In addition to timely watering after each fertilization, jujube needs to be watered once before germination to promote germination, branch and leaf growth and flower bud differentiation. Jujube needs a lot of water to blossom and set fruit, and it must be watered in case of drought at flowering stage. Watering at flowering stage can not only meet the water demand for branch and leaf growth, but also meet the insemination process of pollen germination and improve the fruit setting rate. When drought occurs in the young fruit stage, the leaves will compete with the young fruit for water, causing the young fruit to fall off, so it should be watered in time. In addition, spraying water at flowering stage can promote pollination and fertilization through orchard humidity.
